Abstract

Abstract A bonnet type steamer including an ultrasonic atomizer for generating a mist at room temperature and an electric heater for heating the mist for the generation of steam before the mist enters into the interior of a bonnet where the customer's head is inserted for hair treatment. Specifically, the steam is ejected from the entire periphery of the bonnet while running upward within the bonnet. Control circuitry made up of a microprocessor senses and regulates the temperature of the steam with the aid of a temperature sensor. The temperature of the steam and the duration of operation of the steamer are easily selectable and adjustable by the use of manual switches. A hot air generator is provided for generating hot air for drying purposes.

Claim 6
Dependent Claim 106 words
A bonnet type steamer comprising: a bonnet having a fluid passageway; an atomizer means for generating a mist at room temperature; means for supplying the mist from said atomizer means to said bonnet through said fluid passageway and heater means provided in said fluid passageway for heating said mist from said atomizing means to steam; and a hot air generator means for generating hot air and means for supplying the hot air to said fluid passageway, wherein said steamer serves not only as a steamer by the use of said atomizer means but also as a drier by the use of said hot air generator means.
Claim 7
Dependent Claim 106 words
A bonnet type steamer comprising: a bonnet having a fluid passageway; an atomizer means for generating a mist at room temperature; means for supplying the mist from said atomizer means to said bonnet through said fluid passageway and heater means provided in said fluid passageway for heating said mist from said atomizing means to steam; and a hot air generator means for generating hot air and means for supplying the hot air to said fluid passageway, wherein said steamer serves not only as a steamer by the use of said atomizer means but also as a drier by the use of said hot air generator means.
Claim 8
Dependent Claim 33 words
The bonnet type steamer as set forth in claim 5 wherein said hot air generator means comprises an air blower means for drawing air, said drawn air being heated by said heater means.
Claim 9
Dependent Claim 26 words
The bonnet type steamer as set forth in claim 5 wherein said atomizer means is disabled when said steamer is desired to serve as a steamer.
Claim 10
Dependent Claim 37 words
The bonnet type steamer as set forth in claim 5, further comprising a first shutter means for preventing said hot air from moving into the interior of said bonnet when said steamer is functioning as the steamer.
Claim 11
Dependent Claim 27 words
The bonnet type steamer as set forth in claim 8 further comprising a second shutter means for preventing said hot air from entering into said atomizer means.
Claim 12
Dependent Claim 24 words
The bonnet type steamer as set forth in claim 5 further comprising a mode display means for displaying the operative mode of said steamer.
Claim 13
Dependent Claim 104 words
A bonnet type steamer comprising: a bonnet having a fluid passageway; an atomizer means for generating a mist at room temperature; means for supplying said mist from said atomizer means to said bonnet through said fluid passageway; a heater means provided in said fluid passageway for heating said mist from said atomizing means to generate steam; switch means for presetting the temperature of said resulting steam; a sensor means for sensing the temperature of said steam being generated; and a control circuit means for equalizing the temperature of said resulting steam to said preset temperature in response to the output of said sensor means.
Claim 14
Dependent Claim 104 words
A bonnet type steamer comprising: a bonnet having a fluid passageway; an atomizer means for generating a mist at room temperature; means for supplying said mist from said atomizer means to said bonnet through said fluid passageway; a heater means provided in said fluid passageway for heating said mist from said atomizing means to generate steam; switch means for presetting the temperature of said resulting steam; a sensor means for sensing the temperature of said steam being generated; and a control circuit means for equalizing the temperature of said resulting steam to said preset temperature in response to the output of said sensor means.
